Suaeda asparagoides (Miq.) is a salt marsh plant, long been prescribed in traditional medicine for the treatment of hypertension and liver toxification in Asian countries. The powder of S. asparagoides was added at the ratio of 0, 5, and 10%, respectively, of grain-type Meju to manufacture Doenjang in brine according to the salt concentration (8 and 12%). After 24 weeks of fermentation, the Doenjang samples were determined to have an anti-inflammatory effect on RAW 264.7 cells. Evaluation of the anti-inflammatory effect of Doenjang added S. asparagoides powder extracted using 80% EtOH, was performed to study the inhibition of pro-inflammatory factors such as NF-κB (nuclar factor κB), NO (nitric oxide), TNF-α (tumor necrosis factor alpha), IL-6 (interleukin-6), iNOS (inducible nitric oxide synthase), and COX-2 (cyclooxygenase-2) in lipopolysaccharide (LPS)-induced RAW 264.7 cells. The results showed that the Doenjang extracts reduced the production of NO, IL-6, COX-2, and iNOS increased in the LPS-stimulated RAW cell without cytotoxicity. In the case of the NF-κB and TNF-α there was no significant difference between the control and samples. In conclusion, these results suggest that Doenjang added with the S. asparagoides powder acts as functional fermented food with anti-inflammation effect.

This study evaluated the quality characteristics of dried noodles prepared with doenjang powder (0, 3, 6, 9%) in order to determine the most preferred noodle recipe. The proximate composition of the composite doenjang powder-wheat flours was as follows: calories 365 kcal, carbohydrates 79 g, saccharides 3 g, protein 10 g, fat 0.8 g, and sodium 65 mg. As the level of doenjang powder increased, the content of total amino acids increased; aspartic acid, glutamic acid, tyrosine, and lysine contents increased, in particular. Water-binding capacity decreased as the level of doenjang powder increased. When viscosity of composite doenjang powder-wheat flours was measured by amylography, gelatinization point increased as the level of doenjang powder increased. As the level of doenjang powder increased, L value decreased, whereas a and b values increased. Weight, water absorption, and volume of cooked noodles decreased, whereas turbidity of soup increased. For textural properties, hardness decreased, whereas springiness increased as the level of doenjang powder increased. For overall preference according to the results of sensory evaluation, noodles added with 3% doenjang powder were the most preferred. According to the results, addition of doenjang powder positively affects the overall sensory evaluation of dried noodle, and 3% is the optimal level for addition.

본 연구는 세이지의 다양한 생리적 기능성과 우리 전통된장을 접목하여 허브를 첨가한 된장을 개발하고자 된장의 염도와 세이지분말 첨가량을 달리한 후 반응표면분석법으로 최적조건을 얻고자 관능특성을 조사하였다. 그 결과, 색은 1.20~2.70, 냄새는 1.60~3.20, 맛은 1.40~3.50, 조직감은 1.60~3.50, 전반적인 기호도는 1.60~3.05의 값을 나타내어 실험구의 조건에 따라 차이를 보였다. 이차회귀식에 의하여 형성된 반응표면 분석

매실을 건조한 분말과 농축액을 각각 0.5%, 1.0% 첨가한 된장을 만들고 숙성하면서 품질특성의 변화를 고찰하였다. 된장의 숙성 기간이 경과함에 따라 수분함량은 다소 증가하였으며, 특히 숙성 2주의 수분함량 증가가 다른 기간에 비하여 현저하였다. 된장 숙성중 전질소의 함량은 큰 차이를 보이지 않았으나 아미노태 질소 함량은 숙성 기간 중 지속적으로 증가하였으며, 숙성 2주 동안의 증가가 현저하였다. 매실분말 및 매실 농축액 첨가구에 비하여 대조구
